COVID-19 data initiatives. Initiatives are categorized by data type, public/private access, and individual- or aggregate-level data. Inventory resources classified as Individual indicate that case-level data (protected health information, limited data sets, or HIPAA “deidentified” data) is available to users of the resource. Resources classified as Aggregate indicate that summaries and averages are available to users of the resource. Bubble size = estimated size of available data. The colors indicate the types of data available to users of the resource. Only resources with a website and contact information are included (see Table 2 for URLs of individual resources and the scale of each resource).
